Pre – Installation Checklist
· Does the unit fit through the loft hatch?
· Check there are no obstructions in the hallway or landing where the diffuser is to be fitted and in the loft space above.
· Ensure the loft has adequate cross-flow ventilation to provide a supply of fresh air to the unit.
· Check that all partition walls are intact. Seek building advice if any are missing or broken.
· Check for flued appliances drawing air from the loft, the user should be made aware of any of these.
· Check that any flue passing through the loft is undamaged. Seek building advice if any are damaged or broken.
· Repair any ceiling gaps which allow air leakage into the loft.
· Ensure any loft water storage tanks are covered and sealed.
About the ventilation unit
The damppro loft unit is a Positive Input Ventilation (PIV) unit which creates healthy living environments by supplying filtered air into a property at a continuous rate through a ceiling mounted diffuser. The diffuser is normally installed in a hallway or landing area.
The units have been developed to improve indoor air quality and reduce condensation and mould problems.
In conditions between 19°C – 25°C the units will increase air flow rate by 10%. In hot conditions above 25°C the units will temporarily switch off to avoid bringing hot air into the property from the loft space.
